A postmortem on the dead man’s remains was due to get underway this morning.

The road where the shooting occurred, between the Premier Business Park and Cappagh Road, remains sealed off pending the arrival of the Garda Technical Bureau this morning and traffic delays are expected.

Gardaí were also due to begin examining CCTV footage of access points to and from the road where the fatal attack occurred in an effort to establish how the killer got to and from the scene and if he had assistance.
